Data collection: linear motion name: abstract; include instead of these lines the objectives of the lab (what you investigated), the short description of how you did it and the conclusions formulated based on the obtained results. it should be ½ to 1 page long . data table 2: rolling a ball along a horizontal surface time (s): 2-m distance time (s): 4-m distance time (s): 6-m distance trial 1 trial 2 trial 3 average time (s) avg. velocity(m/s) data table 3: time trials to drop an object 2 m item data trial 1 drop time, t, (s) trial 2 drop time, t, (s) trial 3 drop time, t, (s) trial 4 drop time, t, (s) trial 5 drop time, t, (s) trial 6 drop time, t, (s) trial 7 drop time, t, (s) trial 8 drop time, t, (s) trial 9 drop time, t, (s) trial 10 drop time, t, (s) average drop time (s) t2 (s2) experimental g = 2d/t2 (m/s2) questions: 1. complete the following exercises. 1mi=1609 m 250mi/h= m/s mi/h= 250m/s 2: examining how the ball’s average speed varies with time based on data table 2. similar with the example 5 from lab manual page 65 (procedure) or the hol website “exercise 2” calculate the average speed for every 2m of the 6m traveled by the ball. these are different values than what you calculated in table 2. v1= speed of the ball for the 0-2 m v2= speed of the ball for the 2-4 m v3= speed of the ball for the 4-6m 3. a man walks 3 miles east in 1h at constant velocity, then walks 2 miles east at a constant velocity in 20 minutes, then 2 miles east at a constant velocity in 40 minutes, then rests for 1h and then turns around and walks 8 miles west for 2h. 1. draw a position vs time graph 2. draw a velocity vs time graph 3. draw a vector diagram (use a vector for each segment of the trip). 4. what is the displacement for the entire trip? 5. what is the average speed for the trip? 6. what is the average velocity for the trip? 3. what sources of error were involved in this experiment and how could the amount of error be reduced?
